Fixed Normalmaps

This has been something that has been broken for about 10 years, entirely on accident in part due to the original texture artist that has worked on Black Mesa. Basically, the normalmaps were formatted incorrectly and were OpenGL format, this is a problem because source renders its enviroment in DirectX, so casted shadows on the models were basically inversed and incorrect, where there was depth instead was elevation on the normal and vice versa.

This fixes that by simply converting the OpenGL normalmap to DirectX and it drastically improves character lighting, mostly noticeable on the vests and bodies of guards, Scientists pants, and Marines gear.


If you want the source decompressed .TGAs just ask for them.
